Just the answer this time around okay buddy.
1/3(10x8)(12)=320 in^3
answer: 320 in^3
The appropriate choice is
... D) x = -2 ±√7
Answer:
x = 40
Step-by-step explanation:
x/10 = 4
Multiply each side by 10 to isolate x
x/10 *10 = 4*10
x = 40
Answer:
And we can find this probability with this difference:
And in order to find these probabilities using the normal standard distribution or excel and we got.
So we expect about 99.735% of values between $29 and $89
Step-by-step explanation:
Let X the random variable that represent the amount of Jens monthly phone of a population, and for this case we know the distribution for X is given by:
Where and
We are interested on this probability first in order to find a %
The z score is given by:
If we apply this formula to our probability we got this:
And we can find this probability with this difference:
And in order to find these probabilities using the normal standard distribution or excel and we got.
So we expect about 99.735% of values between $29 and $89
Answer:
x = 3
Step-by-step explanation:
x + y = 3
2x- y = 6
Get the first equation and solve for y
y = 3-x
Now plug in into the 2nd equation
2x - 3 + x = 6
3x = 9
x = 3
